Circle Systems Product Listing

Materials for Wet-Method Magnetic Particle Inspection

MI-GLOW #106 - Black particles for use in a solvent carrier for detecting fine defects, certifiable to AMS 3041 and other documents.

MI-GLOW #800 - Low background, high sensitivity and durability fluorescent particles for use in a solvent carrier. Certifiable to AMS 3044 and major aerospace specifications.

MI-GLOW #810 - MI-GLOW #800 fluorescent particles premixed with powdered WETTING AGENT 100 for use in water media. Certifiable to AMS 3044 and major aerospace specifications.

MI-GLOW #850 - Distinctive red particles for UV and/or visible light with a pre-proportioned powder water conditioner. Can be mixed with water to the best concentration to match lighting conditions.

CIRCLESOL M - A high flashpoint petroleum solvent specifically designed for use in magnetic particle inspection. Meets the requirements of AMS 3161, AMS 2641, DOD-F-87935, and Pratt & Whitney 1887.

Advanced Concentrates for Water-Bath Systems

MI-GLOW #778 - MI-GLOW #800 fluorescent particles premixed with liquid WETTING AGENT 771 for use in water media. Advance formulation allows for conversion to water bath from solvent bath for many applications. Certifiable to AMS 3044 and major aerospace applications.

MI-GLOW #820 - Nonfluorescent black particles premixed with liquid WETTING AGENT #771 for use in water media. Higher particle concentration provides heavier indication buildup for easy detection under visible light conditions.

CIRCLESAFE Aerosols

CIRCLESAFE 778-A - Aerosol spray can version of MI-GLOW #778. Carbon dioxide propellant for odor-free, fume-free inspection Excellent for detecting fine defects in confined areas. Packaged 12 cans per carton.

CIRCLESAFE 800-A - MI-GLOW #800 fluorescent particles and CIRCLESOL M solvent packaged ready-to-use in an aerosol can. Carbon dioxide propellant. Packaged 12 cans per carton.

CIRCLESAFE 820-A -Aerosol spray can version of MI-GLOW #820. Carbon dioxide propellant for odor-free, fume-free inspection. Packaged 12 cans per carton.

CIRCLESAFE 850-A - Unique red particles are visible in ambient light and may be enhanced with UV. Ideal for inspection on welds and applications where high sensitivity is required but a dark environment for UV is difficult to attain. CIRCLESAFE 850-A also uses the conditioned water and carbon dioxide propellant. Packaged 12 cans per carton.

Dry Method Powders

60 Series - These powders are available in four different colors. They are highly refined in order to detect minute discontinuities, and conform to specifications AMS 3040, ASTM E-709, ASME Section V, and MIL-STD-271F(Ships).

70 Series - Fluorescent orange/red and fluorescent green powders meet the criteria of 60 Series powders.

Fluorescent Magnetic Particles for Underwater Nondestructive Testing

MI-GLOW UW #1- Bright pink particles are visible in natural light and fluoresce in UV light. Slightly larger particle size for better enhancement of larger defects.

MI-GLOW UW #528 - Bright red particles are visible in natural light and fluoresce in UV light. Finer, lighter particles remain in suspension longer and enhance finer defects.
